In this blog post, we will talk about the topic of nutrient in I/GCSE Biology. Let's get started! 🥰

• Serious health problems due to poor diet and lack of exercise
• Too much sugar, lack of fruit and vegetable

In I/GCSE Biology, you have to remember the following terms

1. Carbohydrates and fats provide energy (alive/active)
2. Proteins, vitamins and minerals – grow and replace damaged cells and tissues

• Varied diet ➡️ good
• Malnutrition ➡️ wrong amount of nutrient eaten
• Deficiency disease ➡️ not enough of a certain vitamin or mineral
• Keep balanced/healthy diet

It's commonly asked in I/GCSE Biology!!

More exercise ➡️ more energy needed

• Chemical reactions in body release energy from food

Metabolic rate ➡️ speed at which your body uses that energy

• Energy needed for breathing, digestion, keep heart beating (when resting)
• Resting/Basal Metabolic rate ➡️ rate when resting
• Higher metabolic rate ➡️ more energy you use
• Exercise increases metabolic rate
• Exercise increases proportion of muscle to fat in body
• Metabolic rate also affected by inheritance, lifestyle
• Metabolic rate decreases with age

It's also crucial that you have to remember what cholesterol is inI /GCSE Biology!

• Cholesterol ➡️ a fatty substance transported by blood
• Cholesterol ➡️ keeps boy cells functioning normally
• Blood cholesterol levels depends on amount of fat in diet (also inheritance)
• High blood cholesterol levels ➡️ increased risk of diseases from heart and blood vessels

And we're done with this topic! Well Done!
